EDGAR E. PHINNEY, OF NEW YORK, N. Y., ASSIGNOR TO MONROE CALCULATING MACHINE COMPANY, OF NEW Specification of Letters Patent.

YORK, N. Y., A CORPORATION OF NEW YORK. CARRYING MECHANISM FOR CALCULATING-MACHIN ES.

Patented July 9, 1918.

Application filed August 27, 1915. Serial No. 47,644.,

To all whom it may concern:

Be it known that I, EDGAR E. PHINNEY, a citizen of the United States, resident of New York, in the county of New York and State of New York, have made a certain new and useful Invention in Carrying Mechanism for Calculating-Machines; and I declare the following to be a full,'clear,

and exact description of the same, such as will enable others skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or ii res of reference marked thereon, which o i'm a part of this specification.

Figure 1 is a sectional view of a calculating machine showing the invention applied thereto.

Fig. 2 is a detail side view of one of the reciprocatory pawls or teeth, as applied, with the plunger depressed and the pawl moved into engagement with the intermediate gear.

Fig. 3 is a similar view with the plunger and pawl in normal position.

Fig. 4 is a detail side view of one of the pawls or teeth.

The invention has relation to carrying mechanism for calculating machines of the type shown in my co-pending application for letters Patent, Serial Number 41,343, and in the reissue patents to Baldwin, dated December 8, 1914, No. 13,841 and No. 13,842, and particularly to the pawls or teeth of such carrying mechanism, the obto provide carrying pawls or teeth that will move in a straight ath, and to simplify the manufacture an assemblage.

The invention consists in the novel conof parts, as hereinafter set forth.

In the accompan ing drawings, illustrat-. ing the invention, t the shaft of the carrying mechanism, havmg thereon a plurality of collars provided each with two radial arms m, m, fast thereto, each radial arm being provided with acarryin awl or tooth 7'. All of these collars are fi xed uponthe shaft, and the carrying pawls are arranged in two oppositely pitched spiral lines, each series or set of pawls extending about one-fourth around the shaft, both, together about one-half around, and the two series nearly intersecte numeral 73 designates ing, or ending adjacent to each other. The carryin mechanism of the patents to Baldwin re erred to may, of course, be used with substitution of the special pawl devices of this application, instead of the carrying mechanism of t e co-pending application, herein described.

4 designates the shaft of the selecting wheels, 5 the selecting wheels thereupon, 13 the registering wheels, 12 the intermediate gears and p, the reciprocatory plungers, working in slots of collars and in clearance holes of the shaft of the intermediate gears, and having ower cam heads 8, and upper beveled ends, engaged by the lateral studs g, wheels, to depress the plungers so that their heads will, in the rotation of the carrying primary or mechanism, be in position to engage and throw the pawls or teeth of said mechamsm.

' These pawls, in the present case, slide laterally, to one side or the other, in strai ht paths in'directions parallel to the shaft 3, in guideways of the radial arms m, the pawls being usually of rectangular form, provided with open-end notches or recesses 0, at each end, forming upper and lower straight end arms r, 0*, parallel to said shaft, the upper arms sliding in guideways n, and the lower arms slidingin guideways or perforations t, of the opposite members of the radial arms. The guideways n and t have straight walls parallel to the said shaft. The pawls are returned to normal positionby suitable springs, as coiled springs u, after operation by the camheads of the plungers. plungers are returned to normal osition by radial arms 14, fast upon the sha of the carrying mechanism and located midway of the registering The between the two series of carrying memanism including. independently movable I gears, a reciprocatory plunger for each gear, a rotary shaft, members upon said shaft having guideways. provided with straight portions parallel to said shaft, reciprocatory teeth having straight. portions parallel to said shaft and slidable in straight paths-in said guideways against the straight'portions thereof, and means for depressing th'efplnngers individually once during each rotation of the corresponding 10 gears, each of said teeth being engaged by of said shaft and thrown inthe shortest path into engagement with the succeeding gear.

In testimony whereof I aflix' my signature 15 in presence of two witnesses. v EDGAR Ea PHINNEY. Witnesses:
